Great images are generally not created because of the gear you have. It's about the time and energy you put into perfecting your art and learning to see the light, compose an image and use the gear you have to create the image you envision.
Any modern camera is capable of shooting almost anything you want, and all are excellent tools for today's photographers. Think long and hard about what you photograph, where, and how you shoot before purchasing new gear.
Have fun, make mistakes, ask questions, practice, practice, practice – former Gear Acquisition Addict (GAS) addict.
